In a nutshell, no.
Long answer... If D* was not able to handle the metadata to rebuild the 2:3 pulldown, you'd probably end up seeing jerkiness in the video. Macroblocking is not related to the IVTC "feature" of MPEG-2.
I would hope that the pizza-pan dish providers would get high quality video feeds, via fiber, in the SF area, especially from the network affiliates.
But, the pizza-pan dish providers over compress the locals in order to be able to get more locals onto their birds, resulting in macroblocking.
Your best best for the best video is via OTA. While that also varies depending on where the viewer lives, it can't be any worse that what cable-cos or pizza-pan dish providers do to the video.
Unfortunately, the only place to get the best video is via the network feeds. Once the video is destroyed by the network affiliate, and/or cable-co, and/or pizza-pan dish provider, you are stuck with crap.
Sorry to say that pristine video for the consumer is not in the cards.
